A Late-time Radio Survey of Short Gamma-ray Bursts at z  <  0.5: New Constraints on the Remnants of Neutron-star Mergers

A Late-time Radio Survey of Short Gamma-ray Bursts at z  <  0.5: New Constraints on the Remnants of Neutron-star Mergers

Massive, rapidly spinning magnetar remnants produced as a result of binary neutron-star (BNS) mergers may deposit a fraction of their energy into the surrounding kilonova ejecta, powering a synchrotron radio signal from the interaction of the ejecta with the circumburst medium. Here, we present 6.0 ...

Zusammenfassung:Massive, rapidly spinning magnetar remnants produced as a result of binary neutron-star (BNS) mergers may deposit a fraction of their energy into the surrounding kilonova ejecta, powering a synchrotron radio signal from the interaction of the ejecta with the circumburst medium. Here, we present 6.0 GHz Very Large Array (VLA) observations of nine, low-redshift short gamma-ray bursts (GRBs; z
